Issues with traffic, safety, and pollution are just a few of the major transportation-related concerns that modern civilization must contend with. Information and communication technology are playing an increasingly essential role in modern transportation networks. Car companies are working on sensors that may be installed inside vehicles and used for many purposes, such as safety, traffic control, and entertainment systems. Cameras and sensors installed along roadways are helping government agencies monitor traffic and environmental factors. Intelligent transportation systems may be realized by the seamless integration of vehicles and sensing devices, which allows for the exploitation of their sensing and communication capabilities. We discuss the potential benefits of sensor technology for transportation infrastructure connectivity, entertainment applications, and traffic control in an STS, as well as the ways in which a network of sensors embedded in different components of an STS may enhance these areas over time. We wrap up by outlining some of the obstacles that must be overcome before an STS environment can be completely operational and cooperative.
